No sex drive?

Lauren • Married. Me - 21 Him - 24 TTC #1 since 12/14
Okay so I'm 20 years old and I've always had a high sex drive. If anything I was hypersexual. My husband and I have been married three months and all of a sudden I just have no drive at all. I don't think it's or relationship. I am not sitting and wishing he were someone else or masturbating. It's so frustrating because we are ttc #1 and he obviously is a man and needs sexual attention. Any advice or ways to get things going?
